Hello list!
I have an Omni V model 562 serial No. 23a 10489.
I am interested in the production modification below:
Be sure they did the one mentioned in *QST*'s review (Nov 1990 *QST*, p =
33) under the Rough Edges subhead. That one, "incorporated into all =
production units since the spring of 1990," bears directly on just the =
type of hiss you mention.
I find that the radio does exhibit the hiss mentioned, which appears to =
have something to do with the AGC. With AGC off, the hiss is gone, but =
with AGC on there is a hiss present, which is most pronounced on signals =
in the range S1 to S5 on the meter.
The same hiss can be heard by adjusting the RF gain control to between 3 =
o' clock and midday positions, especially if a dummy load is connected.
Any information would be appreciated!
Thanks and 73.. Paul MW0CDO in Port Talbot South Wales UK.
